The refrigerant used in a refrigeration system depends on the type of system and its application.

• Common refrigerants include R-22, R-134a, and R-410A.

• Refrigerants are chosen based on their thermodynamic properties, safety, and environmental impact.

• Newer systems often use more environmentally friendly refrigerants like R-410A.

• Refrigerants must be handled and disposed of properly to prevent harm to people and the environ

The main part of refrigeration is the refrigeration cycle.

• The refrigeration cycle is a continuous process that removes heat from a space and transfers it to the surroundings.
